| theme unit and which is inserted teaching situation | Unit 2 Electromagnetic Phenomena. Topic 3.2: Ohm's Law Curriculum content: -current- potential difference-resistance -series and parallel circuits Calculation of current-using Ohm's law -voltage Calculation of series and parallel circuits -resistive series and parallel circuits. |
| Selection and Justification of resources (fixed picture, Video or Podcast). |
video Students will identify, in a dynamic manner the accuracy of theoretical calculations and thus compare results. should include a podcast with an explanation of the physical phenomenon observed in each case we supplement the video.
|
| Time at which the resource will be used: Beginning, development or closure of the issue within its initial project. | The use of video is used after the preparation of each experiment, after work, to do the video making as a theoretical verification test and attach the explanation of the podcast. |
| List and explain the digital skills | must manage Basic video editing, cut, paste, append, delete and delete. The inclusion of titles in every part of the experiment to document is essential to know which of the subjects being treated. Justification must learn to take video and manipulate each experiment in order to report properly, taking into account all the concepts. This way they can identify what can be observed through a measurement on an instrument and make comparisons with the video to derive other more complex concepts such as instantaneous power or RMS power. basic audio editing, cutting, paste, edit. Eliminate unnecessary noise. Using Audicity programs and Windows Movie Maker for the preparation of his explanation Justification: This is necessary to indicate according to the video, the concept being measured and what was the theoretical result formulas. The concept name Espedificarán compared and measured.

| Description of activities |
| Activities classroom
the student is shown the theoretical development of each experiment, with the explanation of each item and each mathematical formula applied in the actual exercises carried out.
| For the teacher: 1. concepts are defined, current, resistance and voltage 2. power consumption are illustrated in various devices, from their own calculator, to white goods appliances and toys. 3. define the concepts of charge, ideal voltage source, instantaneous voltage, peak voltage, intrinsic resistance 4. defines the concept of circuit. 5. Showing basic series and parallel circuits with equal resistors with different resistors. 6. formulas are provided to calculate current, voltage and resistance in parallel and series circuits.
|
| For the student: 1. Proposes 5 examples of devices to which they can use to verify Ohm's law. 2. Apply formulas in these devices to understand the differences in power consumption resulting from differences in their intrinsic resistance. 3. Learn to distinguish a series of a parallel circuit with resistors and incandescent lamps simple 4. Solve problems for a circuit based and problems in series and parallel circuits.

| extra class activities
can siladin review in the efficient use of a multimeter to prevent accidents or to crash the computer. | For the teacher: 1. Blog Post on the procedure for the activities of each unit practice. 2. Give guidelines for reporting results and how each experiment was performed. 3. Post safety warnings on the dangers of handling currents or high voltages. 4. Include the list of materials and equipment, this includes in particular the use of a multimeter, various appliances and the use of lamp bulbs deaf to assemble circuit soldering iron and solder. 5. Publication of guides use Windows Movie Maker or other video processing software. 6. Publication guides use the meter and connection ways to measure voltage, current and resistance.
|
| For the student: 1. Each team will create a script for an audio and video for explanations and video footage of each experiment, respectively. 2. Each team recorded the experiment on video and will include an explanation of it with a podcast to explain details that are not contemplated or experiences during the process or difficulties they have had to produce of each video. 3. Each team will produce 2 experiments previously assigned to avoid duplication of concepts. 4. Each student of each team must review the material published by all teams and external concerns and opinions of the experiment by a comment left on the blog. 5. The videos created and the scripts of each team must be posted on their blogs and should publish an explanation of why they think that there were differences between their theoretical calculations and measurements. 6. be required to practice as outlined in published guidelines for proper use of the maturity model in subsection D2.2 Production of images, audio and video files using Audacity and Movie Maker |
| Evidence of the status of teaching | students publish on their blogs and videos team made and the scripts (audio and video) of the experiments assigned also have to haer a written reflection on each of the experiments reported by the other teams in identifying procedural errors, conceptual or applied calculation formulas. |
